IMPROVEMENT IN MACHINE-OILERS.

Specification forming part of Letters Patent No. 202,729, dated April23, 1878; application filed March 3, 1875.

To all whom it may concern:

Be it known that I, SAMUEL HUTGHINSON, J r., of Salem, of the county ofEssex and State of Massachusetts, have invented a new and usefulImprovement in Machine-Oilers or automatic lubricators; and do herebydeclare the same to be fully described in the following specificationand represented in the accompanying drawings, of which Figure 1 is afront elevation, and Fig. 2 a vertical and transverse section, of anoiler comprising my invention.

The said oiler contains means of compressing the wick to regulate itsdelivery of oil. It also has a wick-carrying tube adjustable lengthwise,the wick-compressing screw being separate from the wick-tube, and alsoadjustable lengthwise in the oiler. Furthermore, the oiler is providedwith a single wick-tube to hold the wick, and such tube is movablelengthwise, or adjustable within. the plug, cap, or cover andfastening-neck of the reservoir.

In the oilers,shown in the drawings of the Letters Patent No. 133,316,dated November 26, 1872, and granted to me, the wick-supporter isrepresented as composed of two separate tubes, one being stationary andthe other adjustable lengthwise relatively to the stationary one.

In my present oiler I have but one wicktube, A, which is represented asdirectly applied to the fastening-neck B, and provided with a screw, a,to screw into and through such neck B. This mode of application of thewick-tube I prefer, although I sometimes dispense with the screw andhave such tube to slide with friction through the neck. When the screw ais used the wick-tube has to be revolved in order to adjust it to bringthe lower end of the wick at its proper distance from the journal orsurface to be oiled. Furthermore, the glass reservoir 0 of my presentoiler is represented as provided with two necks, b 0, extending from itin opposite directions, each being furnished with a metallic cap orcover, d, to screw upon it. From the lower of said covers thefastening-neck e of the oiler is projected, it being a tubular screw.

The screw for compressing the wick f is shown at g as screwed into anddown through the upper cover or cap at, and upon or into the wickprojecting out of the upper end of the wick-tube, or a notch or openingtherein, the whole being so as to compress said wick, in order todiminish or gage the flowage of oil through it.

Frequently it happens that a capillary wick will deliver oil too fast,and consequently waste of oil and other evil results follow therefrom.It is therefore desirable to have a means of regulating the discharge ofthe oil by the wick, or to reduce such as may be desirable, and as thewick-tube has to be movable or adjustable, to properly adapt it to thesurface to be oiled, it necessarily follows that the means ofcompressing the wick should be also movable with or adjustablerelatively to the tube.

By having the wick-compressing screw project through and out of theupper cap d, access to it readily can be obtained to revolve it withoutfirst requiring the removal of the cap.

Having thus described my new lubricator, What I claim as of my inventionis as follows:

1. In an oiler-case constructed as herein described, the wick-tube A,adjustable lengthwise in or with respect to the reservoir 0, and incombination with the adjustable wick-coinpressor g, as and for thepurpose explained.

2. The wick-tube A, projecting through and beyond the neck B and 0,adjustable lengthwise therein, as set forth.

3. The wick-tube A, arranged in and projecting from the case, asdescribed, and up within the oil-reservoir, and provided with a malescrew, or, to screw into the outer case or its cap, or the neck thereof,all substantially as set forth.
